Context-Aware Document Presentation for Mobile Pass Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managing and accessing digitized documents on mobile computing devices is cumbersome and time-consuming, particularly when it comes to loyalty cards, identification cards, coupons, tickets, and boarding passes.
Innovation Solution
Implementing a system that presents documents on a computing device based on context, including time and location, with dynamic updates and intelligent document interfaces that facilitate easy access and management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If documents are stored and managed on mobile computing devices, then document accessibility is improved, but document management complexity increases
Solution Approach 1:
The system pre-loads documents into a cache memory before they are actually needed by the user. The cache controller monitors document access patterns and proactively retrieves documents from remote storage to local cache, so that when users need documents, they are already available locally, eliminating management complexity during actual use.
Solution Approach 2:
A cache controller acts as an intermediary between the user, local cache memory, and remote document storage. This intermediary automatically manages document retrieval, caching, and delivery without requiring user intervention, thereby simplifying the user experience while handling the complexity of document management in the background.
2Loss of information
If documents are dynamically updated with vendor information, then information currency is improved, but data synchronization complexity increases
Solution Approach 1:
The cache controller implements a feedback mechanism that monitors document access patterns, usage frequency, and staleness. Based on this feedback, the system automatically determines which cached documents need to be refreshed from remote storage, updating only those documents that have changed or are about to expire, thus maintaining information currency without continuous full synchronization.
Solution Approach 2:
Instead of synchronizing all documents continuously, the system performs partial synchronization by updating only the specific subset of documents that have been accessed, are expiring soon, or have been flagged as changed by the vendor. This selective updating reduces synchronization complexity while maintaining information currency for relevant documents.
3Speed
If documents are pre-loaded into cache memory, then document retrieval speed is improved, but memory usage increases
Solution Approach 1:
The cache memory allocation is dynamic rather than static. The cache controller continuously monitors document access patterns, usage frequency, and recency (implementing a form of LRU - Least Recently Used - algorithm). Documents that are frequently accessed are kept in cache, while less frequently used documents are evicted to make room for newer or more frequently accessed documents, optimizing memory utilization based on actual usage dynamics.
Solution Approach 2:
The system changes the parameter of cache size allocation based on document priority, access frequency, and estimated future usage. High-priority documents that are likely to be accessed soon are allocated cache space preferentially, while low-priority documents use minimal or no cache resources. This parameter-based allocation optimizes retrieval speed for critical documents while controlling overall memory usage.
Data Source
AI summary
In some implementations, documents can be presented on a display of a computing device based on a context of the computing device. The context can include a current time and/or current location associated with the computing device. The documents can be presented based on a time and/or location associated with the documents. Documents can be downloaded and shared between devices. Documents can be dynamically updated based on document vendor provided information and/or other network based resources. In some implementations, the various graphical interfaces described herein provide access to a variety of document types in an organized and efficient manner.
